Abstract

A magnetic sensor includes an insulating layer, a first MR element, and a second MR element. The insulating layer includes a protruding surface including first and second inclined surfaces. Each of the first and second MR elements includes a magnetization pinned layer and a free layer. The magnetization pinned layer and the free layer of the first MR element are disposed on the first inclined surface. The magnetization pinned layer and the free layer of the second MR element are disposed on the second inclined surface. The dimension of the protruding surface in a direction parallel to the Z direction is in the range of 1.4 μm to 3.0 μm.
